FREDERICK W. GREMMELS, OF KANSAS CITY, MISSOURI.

PNEUMATIC CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 642,112, dated January 30, 1900.

Application filed OctolJerlO, 1899.

To @ZZ whom it may concern:

Be it known that I, FREDERICK W. Gantt MELS, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Cash-Carriers, of which the following is a specification.

My invention relates to cash-carriers for pneumatic cash-carrying systems; and my object is to produce a device of this character which can be opened or closed as easily and quickly at any period of its service as when first installed as a part of the system.

The great objectionable feature of the carriers as at present constructed is the fact that under constant and heavy service their front ends become mashed out of shape, with the result that a considerable effort on the part of the clerks is required to open or close them, this involving in the aggregate a great loss of time, and after their front ends thus begin to jam or telescope it is only a question of a very short time when they have to be replaced by new ends, the bodies being hammered back into shape.

The present invention therefore contemplates the use of a tube having a door-opening and provided with the usual pad and Washer at its rear end, a door normally closing said opening, a spring to automatically open said door when unresisted, aclasp journaled upon the tube and provided with an opening of the same sine and configuration as'the door through which the door may open, and a front end plate which is secured to the front end of the tube by screw-threads and is provided with a shoulder which bears rmly on said tube in order that the end of the latter and not the threads shall sustain the heavy impact incident to the arrival of each carrier at the cashiers desk, where they are arrested by their front ends (provided with the usual pad) striking with more or less force against a solid metal plate arranged for the purpose. It will be understood what strain these carriers are subjected to when the statement is made that sometimes when loaded with from ten to twenty silver dollars they are forced straight down adistanoe of several stories and are arrested by striking said metallic plate.

This strain obviously would soon bend or Serial Nol 733,160. (No model.)

break the rivets usually employed in fasten` ing the front end of the carrier and permit the cap-plate by telescopic action to cramp the clasp journaled on the tube and render it difficult to turn, as hereinbefore suggested.

With the further obj eet in view of produc'- ing a cash-carrier of simple, strong, durable, and inexpensive construction the invention consists in certain novel and peculiar features of construction and arrangements of parts, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in Which- Figure 1 is a perspective view of the carrier when closed. Fig. 2 isa perspective View when open. Fig. 3 is a longitudinal section of the carrier when closed. Fig. 4 is a transverse section of the carrier when closed.

In the said gures, where similar referencenumerals designate corresponding parts, l designates a. cylindrical tube constructed, preferably, of brass and provided with an opening 2, extending the greater portion of its length and around almost half its circumference in order that a coin the size of a silver dollar or paper money may be easily placed in or removed therefrom, and at the junction of one side margin of said opening with its ends the corners are preferably rounded, as shown at 3, while near the opposite corners of said opening hinge-plates 4 are secured internally to the tube in any suitable or preferred manner, said plates carrying a hingerod 5 of the same length as said opening.

6 designates a segmental door which is of size and configuration to fit snugly in the opening 2, and therefore is provided with the rounded corners 6L to snugly engage the corners 3.of the opening 2. At its inner side and opposite corners it is provided with the hingeplates 7, which are fitted snugly into the plates et in the customary manner and pivotally upon the rod 5. A coil-spring 8, mounted upon said rod between the hinge-plates, has one end bearing against the inner side of the tube and its opposite end against the inner side of the door, and therefore exerts c0n tinuously an outward` pressure upon the latter. Secured externally to or formed integral ICO This clasp is provided with an opening 1l of the same or greater size than the door 6 in order that the latter may be automatically opened outward through said opening when Vthe latter registers with the door-opening. The clasp is also provided with an opening or slot 12, which tits at one end, at least, squarely up against the front edge-with respect to the end of the tube-of the plate 9. By providing the clasp with these two large openings itis practically a skeleton, a pair of narrow strips 13 and 14 being the only connection between the end portions of the clasp. This slot or opening 12 is of such width that when the strip 13 bears 'at one edge against the plate 9 the edge of said slot opposite to strip 13 coincides with the free edge of the door opening, and therefore permits the spring to open said door that cash may be placed in or removed from the carrier.

After the door is closed it -may be secured in such position by twisting the tube in the direction indicated by the arrow, Fig. 4, until such movement is arrested by the strip 14 striking against the opposite side of the plate 9. At this time the strip 13 bridges the joint between the tube 1 and the free edge of the door 6, holding the latter reliably closed, as shown at Fig. 4.

To open the door, the clasp is turned in the opposite direction to that indicated by the arrow until such movement is arrested by strip 13 striking the plate 9, and thereby leaving the door free to open.

15 designates a circular plate provided with a forwardly-projecting annular flange 1G of the same diameter as tube 1, but litting snugly in and riveted to the rear end of clasp 10 and bearing against the rear end of tube 1. This relation being established, it is obvious that the clasp may be turned on the tube, but that it cannot slide longitudinally thereon in one direction, while longitudinal movement in the other direction is prevented by the plate 9 fitting snugly against the front edge of slot or opening 12. This method of securing t-he clasp against longitudinal movement is old and is not'claimed per se in this application. Y

A circular pad 18 and iiexible washer 19 are iitted against the rear side of rear end plate 15, and said pad and washer are mounted upon the bolts 20, projecting rearward from plate 15, and are secured thereon by means of the metallic washer 21 and clamping-nuts 22. This arrangement is also common in pneumatic-tube construction.

23 designates a circular plate which bears squarely against the front end of tube 1, but

does not contact with the front end of the clasp,and said plate is provided with a circular externally-threaded flange 24, which screws into the front end of said tube, as shown at 25.

A pair of bolts 26 project forward through plate 23and through the front pad 27, and said pad is secured thereon bythe metallicI plate 28 fitting in a recess in said pad and the clamping-nut 29 engaging the front ends of saidbolts. The method of securing the plate 23 to the tube eliminates all chance of said plate and tube telescoping under any service, and thereby jamming said plate against the front end of the clasp, as now happens, and making the turning of the latter a diffi- 'cult and slow operation.

The mode of operating the clasp upon the tube having been explained, so as to permit the door to be opened by the spring or to secure the door in its closed position, further remark along this line is unnecessary, except that it is obvious that it is absolutely impossible, as long as the front plate 23 maintains its position on tube 1, for the clasp to be cramped. This carrier can be opened and closed with greater rapidity than the old-style carriers, which consist of two cylinders hinged together or a pair of tubes each -having an opening, which makes necessary a rotation of nearly one hundred and eighty degrees before the carrier is completely opened or closed. The object of rounding'the corners at the free edge of the door is to eliminate any possibility of the clerk cutting or scratching her hand or tearing her apparel in manipulating the carrier.

From the above description it will be apparent that l have produced a cash-carrier for pneumatic cash-carrying systems which embodies the features of advantage enumerated as desirable in the statement of invention, and while the drawings illustrate the preferred embodiment of said invention I do not wish to confine myself to the exact form, proportion,or detail construction of the parts shown, but wish to include all changes properly falling within the spirit and scope of the invention.

Having thus described the invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. A cash-carrier, comprising a tube closed at both ends and provided with an opening in its side, a clasp rotatably mounted on the tube and provided with an opening adapted to register with the tube-opening, and a door controlling the tube-opening, substantially as described.

2. A cash-carrier comprising a tube having an opening, a door hinged in said opening, a spring tending to throw said door outward through said opening, and a clasp journaled upon said tube and provided with an opening which is adapted to register with said tube-opening, and thereby permit said spring to sustain endwise the pressure incidental to Io to open said door, substantially as described. l the stopping of the carrier, substantially as 3. A cash-carrier, comprising a tube having described. an opening in its side and its rear end closed, In testimony whereof I affix my signature 5 a Clasp journaled on the tube and provided in the presence of two witnesses.
